Indeed Milburn the Steve Irwin of the Alien Franchise ;)
To be fair though, there have a been a number of discussions on how to attempt to address a good reason for the Space Cobra Petting, being pretty excited, being hand selected by Vickers...
And well Yog thats not one i have heard before.. but that is interesting if the Organism has some kind of Hypnotic ability that causes a Host to Acquiesce to the Organism. Certainly would be a useful Trait to have for the Purpose of Procreative Life Cycle of a Face Hugger type event... if the Hammerpedes Procreate similar.
The Prometheus Re-write i was working on, had Milburn discover smaller worms like in the "Our First Alien" Deleted Scene, when they enter the room he discovers some small worms and goes to study them and put them into a container for Study when they get to the Ship and then he notices a Larger one like the "Our First Alien" Deleted Scene and is all excited, despite Fifields Hesitation, Milburn rushes over to capture it and Fifield says dont touch it... Milburn mentions they have their Suits that would protect them and he grabs the Larger Worm (Similar to the Deleted Scene size) and as its covered in Black Goo its slippy and it grows a bit in his hand and so he drops it, he then goes to get it again and Fifield is saying leave it... so he takes his eyes off where he is facing and slips over some of the Goo and Lands on all Fours..
This is when he then notices the Two Hammerpedes, and he comments on here must me Mommy... the Hammerpede Aproaches and Stands up to Fifield and Hisses and Milburn warns Fifield to not make any sudden movements, Fifield moves and the Hammerpede Turns towards him and so Milburn wistles at the Hammerpede and Waves his hand to get its attention. They both stair at each other (Milburn and Hammerpede) about 4-5 feet away... the Hammerpede then unfolds its raised/flared parts of its head... Milburn senses as with Cobras this is a sign its relaxed.
Then we have the dialog where Milburn is talking to it from the movie.... then Fifield gets Milburns Attention and as Milburn takes his Eyes off the Hammerpede it Darts towards him and as a Reaction Milburn puts out his hand and grabs it...
The Hammerpede then seems to calm down.... Milburn is very intrigued but then... BAM the Hammerpede Tightens around his Arm and the rest of the Scene is the same as the Movie.
Its little changes like this i was making to make better explanation to such scenes... that would have made much more sense..
